WG2229020004 Oil Guide Ring

WG2229020004 is a dedicated oil guide ring for the input shaft of heavy-duty truck HW series transmissions. It is installed inside the input shaft end cover and outside the input shaft oil seal. Its core function is to guide lubricating oil to the bearing, distribute oil evenly and realize oil return circulation, preventing oil leakage and bearing dry friction.

It features good structural rigidity, outstanding wear and corrosion resistance, with dimensional accuracy fully meeting original factory assembly standards.

Compatible with heavy-duty truck models such as Howo, Sitrak and Steyr, it is fully interchangeable with original parts for direct replacement, serving as an essential lubrication component for transmission repair and maintenance.

WG2229020004 oil guide ring is stamped from high-strength cold-rolled steel plate with anti-rust passivation treatment. It features high hardness, excellent wear resistance, and is resistant to deformation and cracking.

Precise oil guide grooves and oil return holes are evenly distributed on the ring body to ensure smooth oil guiding and efficient oil return, providing sufficient lubrication and low temperature rise for the input shaft bearing.

Made to OE standard dimensions with high concentricity, it is easy to install and fits perfectly with end covers and oil seals.

Adapted to harsh working conditions at the front end of heavy-duty truck transmissions, it delivers impact resistance and oil leakage prevention, protects bearings and shafts, and extends the service life of the transmission.
